One of the renco encoders is busted up. First off, are these going to be worth using? I've got 3 gecko g320's to drive these. The shafts are 1/2 inch. For uniformity I am wanting to replace all 3 encoders. Would the E3's from usdigital.com be what I am looking for? Using roton ballscrew 5/8x.200 and preloaded antibacklash nuts. Good setup or not? Any other suggestions? Also what kind of reduction should I be looking for. Where would I come across a 60 volt 30 or 40 amp power supply for it. Would it be enough?
